> If if they offered to keep your named detached from the sequence it wouldn't do much. Your DNA probably has more bits of entropy than your first and last name together. Doesn't help them much to know that you got DNA sequencing done if they don't know who you are. Generally the idea is they already have an anonymous DNA sample and they want to find a person with a potentially matching sample. Having two anonymous samples doesn't help them.
